@marten-seemann commented on this pull request. > +## ChaCha20-Poly1305 Short Header Packet + +This example shows some of the steps required to protect a packet with +a short header. This example uses AEAD_CHACHA20_POLY1305. + +In this example, TLS produces an application write secret from which a server +uses HKDF-Expand-Label to produce four values: a key, an IV, a header +protection key, and the secret that will be used after keys are updated (this +last value is not used further in this example). + +~~~ +secret + = 9ac312a7f877468ebe69422748ad00a1 + 5443f18203a07d6060f688f30f21632b + +key = HKDF-Expand-Label(server_initial_secret, "quic key", _, 32) This should be `secret` instead of `server_initial_secret` here, right? -- You are receiving this because you are subscribed to this thread.
